Kathmandu, August 26, 2026: A massive flash flood struck Nepal’s Rasuwa district near the Nepal-China border on Wednesday, sending a powerful surge of water, mud and rocks through the Bhote Koshi River system and causing widespread damage to homes, roads, bridges and infrastructure.
According to preliminary information released by the Nepal Tourism Board, 384 travellers are currently unaccounted for, including 291 foreign nationals and 93 Nepali nationals. Among the foreign nationals are 105 Indians, while 37 non-resident Indians (NRIs) have also been listed separately. Authorities are continuing to verify the whereabouts and safety status of those included in the preliminary list.
Nepal Flash Flood: What Happened?
The flash flood struck the Bhote Koshi River area of Rasuwa at around 8:30–9:00 a.m. local time on August 26.
The worst-affected areas include parts of Timure and Syaphrubesi, close to the Nepal-China border. Floodwaters carrying large quantities of debris swept through settlements and damaged roads, bridges, electricity infrastructure and other facilities.
The flood also affected downstream areas, with authorities monitoring the Trishuli River system and surrounding districts.
105 Indians Among Travellers Being Traced
The preliminary list released by the Nepal Tourism Board includes:
- 384 travellers in total
- 291 foreign nationals
- 93 Nepali nationals
- 105 Indian nationals
- 37 NRIs
The information is preliminary and is being cross-checked with travel agencies, guides, local authorities and security agencies. Being included on the list does not by itself mean that a person has been confirmed dead or injured.
Many of the affected travellers were in the region while travelling towards the Kailash Manasarovar area in Tibet.
What Is Believed to Have Caused the Nepal Flash Flood?
The exact cause is still being assessed.
Preliminary information indicates that an earthquake may have triggered an ice-rock avalanche or landslide near the Lhende Khola, causing a sudden surge of water into the Bhote Koshi river system. The river flows through the mountainous border region between Nepal and Tibet.
Authorities are continuing to examine the sequence of events. Therefore, the earthquake-related avalanche or landslide should currently be described as a suspected or preliminary trigger rather than a conclusively established cause.
Extensive Damage Reported
The flash flood has caused major damage across the affected areas.
Reports indicate damage to:
- Houses and settlements
- Roads and bridges
- Vehicles
- Border infrastructure
- Electricity facilities
- Hydropower projects
- Telecommunications infrastructure
- Police and security facilities
The Rasuwagadhi border area has also been affected, disrupting movement and communications along an important Nepal-China route.
Rescue Operations Underway
Nepal’s security and emergency agencies have launched search-and-rescue operations across the affected region.
The Nepali Army, Nepal Police and Armed Police Force are involved in the response. Rescue efforts have been complicated by damaged roads, high water levels, debris and difficult mountainous terrain.
Authorities are simultaneously working to establish the status of people whose contact has been lost.
Risk of Further Flooding
Authorities have warned communities near the Bhote Koshi and Trishuli rivers to remain alert.
A blockage in the upstream area is being monitored because a further release of water could create another surge. Residents in vulnerable riverside locations have been advised to move towards safer areas and follow official instructions.
Flood alerts have also been issued in parts of northern India because rivers flowing from Nepal feed into the plains.
Nepal-Tibet Border Also Hit
The disaster has affected the border region on the Chinese side as well. A major mudslide struck the Gyirong border area, damaging roads and disrupting communication and power infrastructure. Emergency response operations have also been launched there.
